asaase. 7

Be it known that I. Erector. V. M CUL- LOCU, a citizen of the UnitedStates, residing I at St. Louis. in the State of Missouri, have inventedcertain new and useful Improvements in Attachments for Traction-Engines; and I do hereby declare the following to be afull,clear. and exact description of the invention, such as will.enableothersskilled in the art to which it apperlains to make and use the same.

{lhisinvcntio'n relates to traction engines .and has special referenceto a novel form of 1 hauling attachment for engines of this description.One object of the invention is to provide means of novel character forreleasably gearing a winding drum to the traction wheels of an engine ofthis description so that if the engine strikes muddy or slippery groundit may be enabled to pull itself out while at the same time the tractionwheels are revolved. v

\Vith the above and other objects in view, the invention consists of anattachment for traction engines comprising awinding drum omitted.

and certain novel gearing arrangements.

The invention further consists in certain novel details of constructionand combinations of arts hereinafter fully described, illustrate( in theaccompanying drawings, and specifically set forth in the. claim.

In the accompanying drawings, like charactors of reference indicate likeparts in the several views, and :-Figure 1 is a partial side elevationof a traction engine showing the device applied thereto. Fig. 2is adetail perspective view of the device removed from the, engine with aportion of the same The numeral 10 indicates the boiler of a tractionengine and on this boiler is mounted the usual driving engine 11. Theboiler and engine 11 are supported on tractor wheels 12 to one of\vhichis attached a driving gear 13. 5 i

At 14; is a shaft which 'is suspended in any suitable manner below theboiler and just in front of the fire-box. On this shaft is keyed apinion I L which constantly meshes with the. gear 13' so that theshaftis rotated whenever the tractor wheels rcvolve, there beingsuitable connection between one of the wheels and" the engine al thoughthis is not here shown as the same forms nopart'of the invention. Uponthe i Specification of Letters Patent.

shaft 14 there als'i'providw'l a second gear 15 which fixed on the shaftin any suitable manner to revolve therewith. boiler and firmly atiaehedthereto is a saddle ing spaced arms 17 each of which has formed at itslower end-a bearing 18, the hearings being alined and adapted toreceivethe journal ends of a shaft 19. Secured to this shaft 19 is adrum :20 on which is wound a hauling cable'fll. T here is also providedon the shaft 19 a gear 22 which is, like the drum, securely keyed to theshaft and this shaft further has at the end adjacent the gear an arm 23pivoted thereon and provided at its outer end with a stub shaft- 2%whcreon is'niounted 'a gear 25. which constantly meshs'with the gear Thegears and 15 are in :iiinemcnt and the teeth of the three geais L3. and25 are of the be caused to mesh aith the gear 15 if the arm 23 beraised. A In order to raise and lower the arm 23 arm has provided nearits outer end an upstanding car 26 over which tits the forked i throughthe forked end and ear to connect the two. Uponthe side of the boiler isa lever 31 one arm of which is connected to the upper end of the' liftrod 2-8 while to the other arm there is connected a reach rod 32 theopposite end of which is connected to a latch lever which is pivoted ona bracket 34, the lever carrying a quadrant 35 wherewith the iatch ofthe latch lever is engageable. c

In the operation of the device the gears indicated in Fig. 1- If theengine. gets stuck in a mud hole the rope 21 is led off to someconvenient position such as a tree and its end there made fast. Thelatch lever 33 is then moved to the rear and this lifts the aim throughthe medium of the reachrod, bell crank and lift rod. As the arm 23 israised thevgears 25 and 15 are brought into engagement and when theengine is started and the tractor wheels 12 revolved, the gear 13 servesto drive the train of gears formedbr the gears 14, 15, 25 and 22, thusrotating the shaft 19 and drum 20. As the drum 20 rotates the cable 21is wound, thereon and materially assists and cause the gears i5 and25 toengage this.

bracket 30 whereon is mounted a bell crank.

15 and 25 are ordinarily out of mesh as Below the i i lilock lfiprovided with dowmvanlly extendsame pitch. By this means the gear 25 may1 acnd 27 of a lift real 28, a pin 29 passing in pulling the engine outof the hole or de-- pression. It is to be observed that the gears in thetrain and the diameter of the drum are properly proportioned so'that thespace traveled over by the wheels 12 will equal the length of ropeorcable 21 wound upon the drum.

There has-thus been provided a simple and efiicient device of the kinddescribed and for the pu1'p0se,speeified.

' Having thus described the inwntion, what is claimed as new, is

A device of the kind described including a shaft, niountedfor rotation,engine actuated means to drive said shaft, a gear fixed on said shaft torevolve therewith, a second 'sha'ft rotatably mounted parallel to thefirst "mentioned shaft andjn advance thereof, a

drum fixed on said second shaft, a gear 20 fixed on said second shaft,an arm pivoted means including a lift rod con'nected to the arm,a bellcrank lever fixed above said. arm and having one arm of the leverconnected to the lift rod, a reach rod connected to the other arm of thebell crank lever, a latch lever connected to said reach rod and aquadrant coiiperating with said latch lever.

In testimony whereof, I afi'ix my signature, in presence of twowitnesses.
